What you'll need:
x1 Hellfire Torch (preferrably a Paladin one, as they are the most expensive)
x1 Friend (whom you trust)

How its done:
1. FWT creates a public game (ie. ptorch 4 ztorch).
2. FWOT joins FWT's game.
3. FWT and FWOT wait in game until an unsuspecting innocent strolls in!
4. FWT opens trade to see the ztorch he is going for.
5. FWT agree's to the trade, and attempts to trade torch for torch in window.

OH NO! IT DUN WERK!

6. Repeat step 5 a few times, each time saying things like.. "wtf" "do you have room" "why isnt it working"
7. At this point one of you two will get smart (either is fine)

The only way to trade torch for torch, is to drop them somewhere private and pick up the other.

8. Explain the situation to your friend in the privacy of the trade menu.
9. It will make sense to him.
10. Inform him to make a random game.
11. Once he leaves, quickly open trade with your FWOT.
12. Trade your ptorch to your FWOT.
13. Exit game.
14. Join random game created by numbskull.
15. Stand at feet and wait for him to drop his torch.
16. Pick up the torch
17. Thank him (I swear to go you skip this step ill strangle your first born, have some manners)
18. WIN
